I think all of your questions would basically be answered by carefully re-reading the rules manual. In any case, I'm going to try my best to help you along little camper.
Probably the most important lesson any of us can learn from this game.
Friendly model already on the board. No free models, no rezzing dead models.
As many times as you have AP to do them.
May want to re-read the rules on prevention flips.
Bells, whistles, joyful yammering. Red Joker means whatever you were flipping for just got a score of 14-if you pull it on a healing flip, you get all your health back.
The wording as far as I have it basically says your straight line would work. Though you'll want to get a second opinion.
Replaced. Current card.
Anything from the Guild. Mercenaries cast +1SS. If you just play Lucius take a gander at his character card...it will tell you exactly what you want to know.
You seem pretty well off. If I were you I'd play a few more games first and then decide based on your experience.
